ice skating with 70-200 2.8L IS USM
 

here i tried using only f2.8 and manually adjusting focus and speeds with my weak reading eyes. focusing was a big issue with even these slow subjects.

still, i wonder with a zacuto z finder, whether focusing would be much easier and the results even better.

ps i turned off the stabilization for these videos
